380 GEOLOGY AND GOLD DEPOSITS OF THE CRIPPLE CREEK DISTRICT. 
STRATTON PROPERTIES ON BULL HILL. 
SITUATION AND DEVELOPMENT. 
The holdings on Bull Hill of the Stratton Cripple Creek Mining and Develop¬ 
ment Company, or of Stratton’s estate, as it is commonly designated, form an 
irregular .area reaching practically to the summit and covering parts of the southern 
and eastern slopes of that prominent point; irregular projecting points include the 
Longfellow claims on the southeast and the Los Angeles mine on the south. On the 
northeastern side the property includes the Zenobia mine, which adjoins the Phar¬ 
macist. The total area is approximately 200 acres. 
The production was derived chiefly from the Orpha May, Mineral Rock, and 
Shurtloff No. 1 veins; accurate figures have not been obtained, but the total amount 
is considerable. From Hills’s Manual the following data are obtainable; they extend 
only to January 1, 1900, but very little ore has been mined on the properties in 
question since that date.

The production of Shurtloff No. 1, Logan, and Mineral Rock mines has not been 
ascertained. 
During the first part of 1903 the Shurtloff No. 1 was worked to some extent 
through the American Eagle shaft, but in the early part of 1904 the entire system 
was idle. Work on the Shurtloff is reported to have been resumed in the latter part 
of 1904. Most of the following notes, except those on the Zenobia, are from reports 
of men formerly connected with the various mines, from a study of the surface, and 
from data obtained from the underground maps. 
The developments are very extensive and comprise a total length of drifts, 
crosscuts, and shafts of at least 60.000 feet. Aside from a great number of smaller 
shafts there are three deep ones—(1) the John A. Logan, 1,400 feet deep, elevation 
of collar 10,472 feet, of sump 9,097 feet; (2) 950 feet east by south of this is the 
Orpha May, 1,264 feet deep, elevation of collar 10,538 feet, of sump 9 274 feet; (3) 
1,200 feet north by west of this is the American Eagle, 1,500 feet deep, elevation of 
collar 10,750 feet, of sump 9,249 feet. All of these are connected by a remarkable 
system of crosscuts and drifts, developed according to the far-reaching plans of 
W. S. Stratton. Level 15, the deepest in the American Eagle, corresponds to level 
12 of the Logan and level 17 of the Orpha May. 
WATER AND GAS. 
The bottom levels of the mines are dry. Gas has proved very troublesome in 
the Logan mine, especially in a crosscut on level 12, 500 feet northwest of the shaft, 
where it issues in large volumes. It is also said to be bad in the long east crosscut on 
level 13 in the Orpha May mine.
